A 44-year-old Grand Haven man already in prison for violating parole has had additional years tacked onto his sentence for numerous Muskegon County business break-ins.

Muskegon County Circuit Judge James M. Graves Jr. on April 28 sentenced George Alan Campbell to three prison sentences of 9½ to 50 years in separate cases of breaking and entering with intent to commit larceny and two of six years four months to 50 years for the same convictions. The sentences are to be served at the same time but consecutive to Campbell's parole sentence.

Campbell pleaded guilty in all the cases March 20 and was sentenced as a fourth-time habitual offender. He was also ordered to pay restitution totalling nearly $35,000 in four of the cases, with the amount to be determined later in the other case.

Campbell was one of several men arrested in numerous West Michigan business burglaries, committed by three unrelated groups of criminals in 2007. A task force that involved more than 20 law-enforcement officers broke all three cases.
